  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

How New Hampshire Property Taxes Work

New Hampshire has both state and local property taxes. In fact, any given property can pay up to four different property taxes: a county tax, a town tax, a local school tax and the state education tax.

To determine the amount on which to base taxes, local assessors conduct annual appraisals. The goal of these appraisals is to calculate the full market value of the property. In general, assessors do not visit properties. They use mass appraisal techniques to determine property values based on market and property data.

That appraisal process is inherently imperfect, and the state of New Hampshire recognizes that different areas have slightly different appraisal procedures. To compensate for appraisal differences, the state equalizes values between counties. This involves applying a ratio to the property’s market value in order to balance the property values between all areas. That ratio is used to determine the state education tax rate, which varies from city to city, as described below.

Homeowners who disagree with their home’s valuation can file an abatement request. That will generally lead to a review of valuation, and a possible refund of taxes paid.

New Hampshire Property Tax Rates

The state and a number of local government authorities determine the tax rates in New Hampshire. Towns, school districts and counties all set their own rates based on budgetary needs. Tax rates are expressed in mills, with one mill equal to $1 of tax for every $1,000 in assessed property value.

As mentioned earlier, there are four different types of property taxes in New Hampshire. Towns collect property taxes which total about County taxes averaged 2.71 mills. There is a local school tax, which averaged $11.33 across the state, and there is a statewide education tax that averages 2.15 mills.

Because mill rates can differ so much between counties and towns, it’s easiest to compare property taxes using effective property tax rates and not mill rates. Effective property tax rates are property taxes paid as a percentage of home value. The table below shows the average effective property tax rate for every New Hampshire county, along with median home value and median annual payments.

Rank County Property Tax Rate School Rating Home Value Growth


Our study aims to find the places in the United States where people are getting the most value for their property tax dollars. To do this, we looked at property taxes paid, school rankings and the change in property values over a five-year period.

First, we used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

As a way to measure the quality of schools, we analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

Then, we calculated the change in property tax value in each county over a five-year period. Places where property values rose by the greatest amount indicated where consumers were motivated to buy homes, and a positive return on investment for homeowners in the community.

Finally, we calculated a property tax index, based on the criteria above. Counties with the highest scores were those where property tax dollars are going the furthest.
